I echo that isPartOf, hasPart and Collection belong to same group of concept, which is for constructing relationships or graphs.

That was actually in my first draft of the email I sent, but I removed it because I couldn't fully communicate the reason (no one won the debate in my head on whether it should be done).

The internal debate is now leaning towards generic Collection, for the reason of modeling Collections that either don't have a representative webpage (probably common enough). It is also a great use case of isPartOf without a hasPart option (where would the hasPart="" live?).

Indeed. At face value it seems odd to have only one one-way arrow in an inherently bidirectional relationship.
